I have heard many people not happy with the Remington Kleenbore Primers. So far I have not had any problems with them, but I do shoot loose powder and I do not have a break open.

If you find that after a few shots the Winchester 209 are hard to remove, an easy fix is take some Q-tips to the range with you. After about several shots, spray a Q-tip with alcohol and clean the inside of the 209 primer area with it. Use the other end to make sure it is dry in there. Just that simple cleaning will make them easy to load and remove again. At least it does in my rifles. I do this all the time with my Black Diamond and my Disc.
